IMPROVEMENT IN THE MODES OF CNNCTING PITMEN TO FLY-WHEELS.

Specification forming part of Letters Patent No. 15L310, dated May Q6, 1874; application filed August 19, 1873.

To all whom it may concern:

Be it known that I, J. M. G. MOUCK, of

l Drakeville, in the county of Davis and the State of Iowa, have invented a new Improvement in Mode of Attaching Pitmeu to VFly- Vheels; and I do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying,` drawing forming a part of this specication, in which is represented a side view of my improved 'wheel7 arranged in connection with an ordinary spring-power mechanism, A B C I O.

rlhe wheel has curved arms F, one of which is provided with a slot. This construction adapts it for attachment of a pitman, J, by means of a wrist-pin, S, which passes through the end of a bar that is pivotcd to the rim of the wheel, and is clamped in any adjustment by a screw-nut.

To allow the pin Gto be adjusted for giving a longer or shorter stroke of the pitman, it is evident the slot must be upon a curve of a circle whose radius is the pivot of bar I.

It is a well-known fact thaty the arms of a y or balance wheel require to be as light, and its rim as heavy, as possible. The curved slot in one of the arms of the wheel D naturally weakens it, and one of the objects of the bar I is to compensate for the loss and prevent breaking or giving way of the arm. Another and more important result is, overbalancing the wheel on one side, so that it has no deadcenter, which, ofcourse, saves power.

I have shown the pitman as provided with a wrist-pin, H, working n .a vertical slot of bar L, which depends from the frame E.

The pitman may be connected with any mechanism drivin by any moter used to impart rotation to the y-Wheel, and, of course, the guide-bar L ma),7 be dispensed with if desirable.

Havingthus described my invention, what I claim is- The combination ,with the ily-wheel D having a curved slotted arm, F, of the bar I, pivoted to the rim thereof, the wrist-pin Gr, and pitman, all as shown and described.
